MANILA, Philippines — Nearly three out of four adult Filipinos support the conduct of a Senate impeachment trial against Vice President Sara Duterte, according to the latest Tugon ng Masa (TNM) survey conducted by Octa Research.
Results of the nationwide survey showed that 74 percent of respondents favor proceeding with the impeachment trial, an increase from the 69 percent recorded in March 2026.
The poll also found that 21 percent opposed the impeachment proceedings, while 4 percent were undecided.
Support for the trial was strongest in Metro Manila, where 84 percent of respondents expressed approval, followed by Balance Luzon at 78 percent and Visayas at 77 percent.
Mindanao posted the lowest level of support at 54 percent. It also registered the highest opposition rate among the major geographic areas, with 41 percent of respondents saying they were against the impeachment trial.
Octa said the findings indicate that support for the impeachment process remains the majority view across the country despite regional differences in opinion.
The survey was conducted from April 20 to 24, 2026 through face-to-face interviews with 1,200 respondents aged 18 years old and above nationwide.
The survey has a margin of error of ±3 percentage points at the 95 percent confidence level. Subnational estimates for Metro Manila, Balance Luzon, the Visayas, and Mindanao have margins of error of ±6 percentage points.
Octa Research described the survey as independent, non-commissioned, and non-partisan.
